He adds that Caren Hagner of the University of Hamburg in Germany has signed the new paper. “We gained much more confidence,” Hagner says.”

INFN press office, “New Tests Confirm The Results Of OPERA On The Neutrino Velocity, But It Is Not Yet The Final Confirmation,” Interactions NewsWire, 18 November 2011. “New tests conducted at the Gran Sasso National Laboratory of INFN by the OPERA Collaboration, with a specially set up neutrino beam from CERN, confirm so far the previous results on the measurement of the neutrino velocity. The new tests seem to exclude part of potential systematic effects that could have affected the original measurement. “A measurement so delicate and carrying a profound implication on physics requires an extraordinary level of scrutiny – said Fernando Ferroni, president of Italian Institute for Nuclear Physics (INFN)”. “One of the eventual systematic errors is now out of the way, but the search is not over. They are more checks of systematics currently under discussion, one of them could be a synchronisation of the time reference at CERN and Gran Sasso independently from the GPS, using possibly a fiber” said Jacques Martino, Director of National Institute of Nuclear and Particle Physics of French CNRS.”

The team also re-checked their statistical analysis, confirming that the error on their measurements was indeed 10 nanoseconds. What they found was “absolutely compatible” with the original announcement, Stanco says. That was enough for Stanco to sign his name to the paper. The team is still running other tests, including measuring the length of a fibre-optic cable that carries information from the underground lab at Gran Sasso to a data-collection centre on the surface. The team is also trying to do the same test using another detector at the lab called RPC. That test will take another several months.”
